A harmful algal bloom, fueled by a marine heat wave, has been choking South Australia’s coastline, turning once-colorful ecosystems filled with thriving marine life into underwater graveyards.
The bloom has killed about 15,000 animals from over 450 species, according to observations on the citizen science site iNaturalist. It has also poisoned more than 4,500 square kilometers (1,737 square miles) of the local waters – an area larger than Rhode Island – littering beaches with carcasses and ravaging an area known for its diversity.
The toxic algal bloom has devastated South Australia’s fishing industry and repelled beachgoers, serving as a stark warning of what happens when climate change goes unchecked.
And once a bloom begins, there is no way of stopping it. Read the full story at the link in @cnn’s bio.

Waste management and resource recovery remain essential to circular progress. The Department for Energy Security and Net Zero’s recent review identified strong potential for circular construction strategies and end‑of‑life reuse in construction to deliver quantifiable carbon savings. Yet challenges persist in the rollout of Simpler Recycling due to legacy property structures. Strengthening these back‑end systems ensures green building products re‑enter value chains, supporting both circular economy objectives and sustainable urban development. The collective impact across policy, design, education, and technology confirms that the carbon footprint of construction can be reduced dramatically when the sector treats sustainability as an integrated, measurable discipline rather than an optional ambition.
